The invention discloses a distributed
cloud storage optimization method oriented to large-scale data, which relates to the technical field of distributed
cloud storage and comprises the following steps of: 1, generating a distribution decision,
label mapping and
time alignment number at an entrance according to a small object threshold and a late access
score, and filing the distribution decision, the
label mapping and the
time alignment number; 2, storing a source object in a storage bucket, synthesizing a composite container according to the identifier, outputting a
list file, an index segment and a pre-write log, and setting a source object retention window; 3, during reading, a cloud side firstly copies a source object to a heat collection
barrel return link by a
server side, and an object side performs container segmentation reading and triggers hot fragment extraction; 4, collecting a standard layer returning proportion or a hot layer returning proportion,
delay and cost, performing closed-loop updating on parameters, and
rewriting and recycling according to a combined triggering amount; according to the method, cross-cloud read-write
collaboration,
caliber consistency and
traceability are realized, long-term cost is reduced,
tail time
delay is stabilized, and
maintainability and expansibility are enhanced.
